A shutdown in the cookie cutter machine was traced to a broken network cable. What are two reasons that explain why using DLR is an appropriate choice for network resiliency? (Choose two)

A shutdown in the cookie cutter machine was traced to a broken network cable. What are two reasons that explain why using DLR is an appropriate choice for network resiliency? (Choose two)
A . DLR is designed for single network operation at the machine level
B . Moving to a linear topology will reduce the number of cables and so reduce risk of cable failure
C . DLR is the only resiliency technology that is supported by CIP Safety
D . Layer 2 resiliency protocols like REP and RSTP do not have a fast enough convergence time for motion control
E . Half of the network traffic goes clockwise on the ring and the other half counter­clockwise, reducing by 50% the impact of cable failure
